<P>
<A NAME="IDX250"></A>

</P>
<P>
When starting a new translation, the translator creates a file called
<TT>&lsquo;<VAR>LANG</VAR>.po&rsquo;</TT>, as a copy of the <TT>&lsquo;<VAR>package</VAR>.pot&rsquo;</TT> template
file with modifications in the initial comments (at the beginning of the file)
and in the header entry (the first entry, near the beginning of the file).

</P>
<P>
The easiest way to do so is by use of the <SAMP>&lsquo;msginit&rsquo;</SAMP> program.
For example:

</P>

<PRE>
$ cd <VAR>PACKAGE</VAR>-<VAR>VERSION</VAR>
$ cd po
$ msginit
</PRE>

<P>
The alternative way is to do the copy and modifications by hand.
To do so, the translator copies <TT>&lsquo;<VAR>package</VAR>.pot&rsquo;</TT> to
<TT>&lsquo;<VAR>LANG</VAR>.po&rsquo;</TT>.  Then she modifies the initial comments and
the header entry of this file.

<A NAME="IDX254"></A>
The <CODE>msginit</CODE> program creates a new PO file, initializing the meta
information with values from the user's environment.

</P>
<P>
Here are more details.  The following header fields of a PO file are
automatically filled, when possible.

</P>
<DL COMPACT>

<DT><SAMP>&lsquo;Project-Id-Version&rsquo;</SAMP>
<DD>
The value is guessed from the <CODE>configure</CODE> script or any other files
in the current directory.

<DT><SAMP>&lsquo;PO-Revision-Date&rsquo;</SAMP>
<DD>
The value is taken from the <CODE>PO-Creation-Data</CODE> in the input POT
file, or the current date is used.

<DT><SAMP>&lsquo;Last-Translator&rsquo;</SAMP>
<DD>
The value is taken from user's password file entry and the mailer
configuration files.

<DT><SAMP>&lsquo;Language-Team, Language&rsquo;</SAMP>
<DD>
These values are set according to the current locale and the predefined
list of translation teams.

<DT><SAMP>&lsquo;MIME-Version, Content-Type, Content-Transfer-Encoding&rsquo;</SAMP>
<DD>
These values are set according to the content of the POT file and the
current locale.  If the POT file contains charset=UTF-8, it means that
the POT file contains non-ASCII characters, and we keep the UTF-8
encoding.  Otherwise, when the POT file is plain ASCII, we use the
locale's encoding.

<DT><SAMP>&lsquo;Plural-Forms&rsquo;</SAMP>
<DD>
The value is first looked up from the embedded table.

As an experimental feature, you can instruct <CODE>msginit</CODE> to use the
information from Unicode CLDR, by setting the <CODE>GETTEXTCLDRDIR</CODE>
environment variable.

<P>
The initial comments "SOME DESCRIPTIVE TITLE", "YEAR" and
"FIRST AUTHOR &#60;EMAIL@ADDRESS&#62;, YEAR" ought to be replaced by sensible
information.  This can be done in any text editor; if Emacs is used
and it switched to PO mode automatically (because it has recognized
the file's suffix), you can disable it by typing <KBD>M-x fundamental-mode</KBD>.

</P>
<P>
Modifying the header entry can already be done using PO mode: in Emacs,
type <KBD>M-x po-mode RET</KBD> and then <KBD>RET</KBD> again to start editing the
entry.  You should fill in the following fields.

</P>
<DL COMPACT>

<DT>Project-Id-Version
<DD>
This is the name and version of the package.  Fill it in if it has not
already been filled in by <CODE>xgettext</CODE>.

<DT>Report-Msgid-Bugs-To
<DD>
This has already been filled in by <CODE>xgettext</CODE>.  It contains an email
address or URL where you can report bugs in the untranslated strings:


<UL>
<LI>Strings which are not entire sentences, see the maintainer guidelines

in section <A HREF="gettext_4.html#SEC19">4.3  Preparing Translatable Strings</A>.
<LI>Strings which use unclear terms or require additional context to be

understood.
<LI>Strings which make invalid assumptions about notation of date, time or

money.
<LI>Pluralisation problems.

<LI>Incorrect English spelling.

<LI>Incorrect formatting.

</UL>

<DT>POT-Creation-Date
<DD>
This has already been filled in by <CODE>xgettext</CODE>.

<DT>PO-Revision-Date
<DD>
You don't need to fill this in.  It will be filled by the PO file editor
when you save the file.

<DT>Last-Translator
<DD>
Fill in your name and email address (without double quotes).

<DT>Language-Team
<DD>
Fill in the English name of the language, and the email address or
homepage URL of the language team you are part of.

Before starting a translation, it is a good idea to get in touch with
your translation team, not only to make sure you don't do duplicated work,
but also to coordinate difficult linguistic issues.

<A NAME="IDX278"></A>
In the Free Translation Project, each translation team has its own mailing
list.  The up-to-date list of teams can be found at the Free Translation
Project's homepage, <A HREF="http://translationproject.org/">http://translationproject.org/</A>, in the "Teams"
area.

<DT>Language
<DD>
Fill in the language code of the language.  This can be in one of three
forms:


<UL>
<LI>

<SAMP>&lsquo;<VAR>ll</VAR>&rsquo;</SAMP>, an ISO 639 two-letter language code (lowercase).
See section <A HREF="gettext_17.html#SEC331">A  Language Codes</A> for the list of codes.

<LI>

<SAMP>&lsquo;<VAR>ll</VAR>_<VAR>CC</VAR>&rsquo;</SAMP>, where <SAMP>&lsquo;<VAR>ll</VAR>&rsquo;</SAMP> is an ISO 639 two-letter
language code (lowercase) and <SAMP>&lsquo;<VAR>CC</VAR>&rsquo;</SAMP> is an ISO 3166 two-letter
country code (uppercase).  The country code specification is not redundant:
Some languages have dialects in different countries.  For example,
<SAMP>&lsquo;de_AT&rsquo;</SAMP> is used for Austria, and <SAMP>&lsquo;pt_BR&rsquo;</SAMP> for Brazil.  The country
code serves to distinguish the dialects. See section <A HREF="gettext_17.html#SEC331">A  Language Codes</A> and
section <A HREF="gettext_18.html#SEC334">B  Country Codes</A> for the lists of codes.

<LI>

<SAMP>&lsquo;<VAR>ll</VAR>_<VAR>CC</VAR>@<VAR>variant</VAR>&rsquo;</SAMP>, where <SAMP>&lsquo;<VAR>ll</VAR>&rsquo;</SAMP> is an
ISO 639 two-letter language code (lowercase), <SAMP>&lsquo;<VAR>CC</VAR>&rsquo;</SAMP> is an
ISO 3166 two-letter country code (uppercase), and <SAMP>&lsquo;<VAR>variant</VAR>&rsquo;</SAMP> is
a variant designator. The variant designator (lowercase) can be a script
designator, such as <SAMP>&lsquo;latin&rsquo;</SAMP> or <SAMP>&lsquo;cyrillic&rsquo;</SAMP>.
</UL>

The naming convention <SAMP>&lsquo;<VAR>ll</VAR>_<VAR>CC</VAR>&rsquo;</SAMP> is also the way locales are
named on systems based on GNU libc.  But there are three important differences:


<UL>
<LI>

In this PO file field, but not in locale names, <SAMP>&lsquo;<VAR>ll</VAR>_<VAR>CC</VAR>&rsquo;</SAMP>
combinations denoting a language's main dialect are abbreviated as
<SAMP>&lsquo;<VAR>ll</VAR>&rsquo;</SAMP>.  For example, <SAMP>&lsquo;de&rsquo;</SAMP> is equivalent to <SAMP>&lsquo;de_DE&rsquo;</SAMP>
(German as spoken in Germany), and <SAMP>&lsquo;pt&rsquo;</SAMP> to <SAMP>&lsquo;pt_PT&rsquo;</SAMP> (Portuguese as
spoken in Portugal) in this context.

<LI>

In this PO file field, suffixes like <SAMP>&lsquo;.<VAR>encoding</VAR>&rsquo;</SAMP> are not used.

<LI>

In this PO file field, variant designators that are not relevant to message
translation, such as <SAMP>&lsquo;@euro&rsquo;</SAMP>, are not used.
</UL>

So, if your locale name is <SAMP>&lsquo;de_DE.UTF-8&rsquo;</SAMP>, the language specification in
PO files is just <SAMP>&lsquo;de&rsquo;</SAMP>.

<DT>Content-Type
<DD>
<A NAME="IDX279"></A>
<A NAME="IDX280"></A>
Replace <SAMP>&lsquo;CHARSET&rsquo;</SAMP> with the character encoding used for your language,
in your locale, or UTF-8.  This field is needed for correct operation of the
<CODE>msgmerge</CODE> and <CODE>msgfmt</CODE> programs, as well as for users whose
locale's character encoding differs from yours (see section <A HREF="gettext_11.html#SEC188">11.2.4  How to specify the output character set <CODE>gettext</CODE> uses</A>).

<A NAME="IDX281"></A>
You get the character encoding of your locale by running the shell command
<SAMP>&lsquo;locale charmap&rsquo;</SAMP>.  If the result is <SAMP>&lsquo;C&rsquo;</SAMP> or <SAMP>&lsquo;ANSI_X3.4-1968&rsquo;</SAMP>,
which is equivalent to <SAMP>&lsquo;ASCII&rsquo;</SAMP> (= <SAMP>&lsquo;US-ASCII&rsquo;</SAMP>), it means that your
locale is not correctly configured.  In this case, ask your translation
team which charset to use.  <SAMP>&lsquo;ASCII&rsquo;</SAMP> is not usable for any language
except Latin.

<A NAME="IDX282"></A>
Because the PO files must be portable to operating systems with less advanced
internationalization facilities, the character encodings that can be used
are limited to those supported by both GNU <CODE>libc</CODE> and GNU
<CODE>libiconv</CODE>.  These are:
<CODE>ASCII</CODE>, <CODE>ISO-8859-1</CODE>, <CODE>ISO-8859-2</CODE>, <CODE>ISO-8859-3</CODE>,
<CODE>ISO-8859-4</CODE>, <CODE>ISO-8859-5</CODE>, <CODE>ISO-8859-6</CODE>, <CODE>ISO-8859-7</CODE>,

<A NAME="IDX285"></A>
<A NAME="IDX286"></A>
When single quote characters or double quote characters are used in
translations for your language, and your locale's encoding is one of the
ISO-8859-* charsets, it is best if you create your PO files in UTF-8
encoding, instead of your locale's encoding.  This is because in UTF-8
the real quote characters can be represented (single quote characters:
U+2018, U+2019, double quote characters: U+201C, U+201D), whereas none of
ISO-8859-* charsets has them all.  Users in UTF-8 locales will see the
real quote characters, whereas users in ISO-8859-* locales will see the
vertical apostrophe and the vertical double quote instead (because that's
what the character set conversion will transliterate them to).

<A NAME="IDX287"></A>
To enter such quote characters under X11, you can change your keyboard
mapping using the <CODE>xmodmap</CODE> program.  The X11 names of the quote
characters are "leftsinglequotemark", "rightsinglequotemark",
"leftdoublequotemark", "rightdoublequotemark", "singlelowquotemark",
"doublelowquotemark".

Note that only recent versions of GNU Emacs support the UTF-8 encoding:
Emacs 20 with Mule-UCS, and Emacs 21.  As of January 2001, XEmacs doesn't
support the UTF-8 encoding.

The character encoding name can be written in either upper or lower case.
Usually upper case is preferred.

<DT>Content-Transfer-Encoding
<DD>
Set this to <CODE>8bit</CODE>.

<DT>Plural-Forms
<DD>
This field is optional.  It is only needed if the PO file has plural forms.
You can find them by searching for the <SAMP>&lsquo;msgid_plural&rsquo;</SAMP> keyword.  The
format of the plural forms field is described in section <A HREF="gettext_11.html#SEC190">11.2.6  Additional functions for plural forms</A> and
section <A HREF="gettext_12.html#SEC211">12.6  Translating plural forms</A>.
